Chuck, Thanks for that clear explanation. It would make perfect sense if my toothed washer had a flat side, but it rotates freely on the steerer. When I get the time in enegy to take the thing apart again, I'll look for tool marks inside the toothed washer. Possibly a previous owner filed out the flat to round.
I do think the french flatted steerer is a better idea than the slotted steerer and keyed washers on standard forks. I can't turn the flatted washer so it buggers the threads. Most keyed washers can rotate so the projecting tab rests against the threads.
